Question

Is there a Common Lisp syntax highlighting .xshd file for use with ICSharpCode.TextEditor? I haven t been able to find one on google, and the format for writing syntax highlighting specification files is so wretchedly documented that I can t make a very good one myself. I can highlight basic keywords, but not much more.

It needs to have the following:

Highlight common lisp keywords, such as list, dolist, read-line. lambda, etc.
Syntax highlighting for the words after defun, defmacro, defvar, etc, such that in the text (defun a () ...), a is highlighted. It doesn t have to be complete because I can add more, just one or two is fine to show how it s done.
Highlight symbols like :a
Highlight quoted lists in both backquote and single quote form, and "unhighlight" escaped forms within quoted lists (escaped by ,, @,, etc)
Highlight the name of a function being called. For example, in the text (a b c), a needs to be highlighted
Optional: anything else that I missed that would be helpful (I m new to lisp so I don t know everything that can be highlighted)

Does anyone know where to get a Common Lisp syntax highlighting file for ICSharpCode.TextEditor that has these features?

Here is a start for a Scheme highlighter. Not very fancy, but shows how recursion works with the rulesets.

<SyntaxDefinition name="Scheme" extensions=".sls;.sps;.ss;.scm"
